Roy Chandler, who owns Gardeners Paradise, in Canterbury, also advises that another money and water saver is to use coconut coir as a mulch because it retains moisture easily and naturally.
He said: “Coir mulch is a natural by-product from the inside of a coconut which in the garden both holds water and drains well keeping plants hydrated. In addition, it slowly breaks down, adding nutrients back into the soil as compost. Coir also helps control weeds and lasts up to three years.”
